Human body signals detection functions in fibers such as visual temperature indicator, are important aspects in future development of satisfying the warmth and comfortableness of conventional textile fibers. A series of reversible thermochromic fibers (VTFs), where thermochromic microcapsules and polypropylene (PP) was used as color indicator and polymer fiber matrix, resp., were prepared via melt spinning in this paper. The temperature-color response behaviors of VTFs were investigated in detail. The SEM images of cross section of VTFs showed that PP was an excellent matrix for the dispersion of thermochromic microcapsules and no aggregation occurred. The results of color measuring and matching indicated that VTFs exhibited various colors of red, purple and blue depending on the mass ratio of the red function and blue function microcapsules. Moreover, when the ambient temperature changed between 5 °C and 35 °C, the color of VTFs could fade and recover in a short time, and this kind of VTFs displayed excellent performance stability after 60 temperature cycles. In the experiment, the researchers used many compounds, for example, Crystal violet lactone (cas: 1552-42-7Application In Synthesis of Crystal violet lactone).

Crystal violet lactone (cas: 1552-42-7) belongs to benzofurans derivatives. Benzofuran derivatives are one of the most important oxygen-containing heterocycles.

Solid phase adsorption of crystal violet lactone on silica nanoparticles to probe mechanochemical surface modification was written by Ichimura, Kunihiro;Funabiki, Akira;Aoki, Ken-ichi;Akiyama, Haruhisa. And the article was included in Langmuir in 2008.Recommanded Product: Crystal violet lactone This article mentions the following:

The solid phase adsorption of crystal violet lactone (CVL) on 5 types of Stober SiO2 nanopowders with BET sp. surface areas in the range of 50-800 m2/g under dry milling conditions was described for the first time. The H bonding between surface silanol and the carboxylate of the ring-opened triphenylmethane dye (CVL+) led to the formation of monolayers of CVL+ in a flat-laid configuration. The λmax of CVL+ in diffusive reflection visible spectra was influenced by the particle size of SiO2 powders, suggesting that the microenvironmental polarity of adsorbed CVL+ is considerably reduced along with the decrease of the particle size. The solid phase adsorption of CVL obeyed Langmuir adsorption isotherms to give a saturated amount of CVL+ for every SiO2 nanoparticle. The surface concentration of CVL+ on nanoparticles at the saturation was estimated to be 0.31 mg/m2 on average, disclosing that about 52% of the surface can be covered by CVL+ under the assumption that the BET-sp. surface areas are equivalent to the real surfaces active for the CVL adsorption. The generation of the blue color of CVL provided a convenient means to estimate qual. and quant. anal. of the surface coverage with surface-active reagents, which conceal surface silanols. Subsequently, SiO2 nanoparticles were milled with a surface modifier, followed by milling with CVL to observe the intensity of the blue color to disclose that the surface coverage with oligo- and polyethylene glycols as well as with nonionic surfactants by dry milling was specifically determined by the number of repeating oxyethylene units. Although the surface-active reagents were easily desorbed in water, the desorption was notably suppressed by milling with CVL, suggesting that the surface-modified particles with the surface-active reagents are covered with ultrathin films of CVL. In the experiment, the researchers used many compounds, for example, Crystal violet lactone (cas: 1552-42-7Recommanded Product: Crystal violet lactone).

In view of the problem that the traditional epoxy resin coating is single in color and cannot meet the requirements of modern interior decoration design, a new type of thermotropic epoxy resin coating is proposed, which is made by using modified epoxy resin PEM and thermo reversible color change microcapsules. The effects of the content of microencapsulated emulsion and the type of curing agent on the properties of the thermotropic re-versible epoxy resin emulsion and the coating film after coating were investigated. The results showed that the con-tent of microcapsule emulsion was 15%, and the coating had high stability and long storage time. And the content of microcapsule emulsion was within 15%. The gloss, impact strength, adhesion and elasticity of paint film de-creased with the increase of microcapsule emulsion content, and the hardness increased. The gloss and elasticity of the coatings prepared by cyclohexadine as curing agent are better. The coating film of the thermotropic reversible color epoxy resin coating film is lighter with the temperature increasing, and the same color change law is shown in the temperature rising and cooling, which proves that the thermotropic reversible color change is good.

More than 40% of the energy generated globally is consumed by residential and com. buildings, so energy efficient materials for buildings are urgently needed at present. On-demand thermal energy storage/release using phase change materials (PCMs) can improve thermal energy utilization efficiency, however, they are facing low adaptability to temperature and easy flammability in the case of fulfilling high thermal management capacity. Herein, we report octadecylamine-based PCMs with tailor-made mol. firefighting and thermal energy management capability. These synthesized octadecylamine-based Schiff base-containing PCMs (SB-PCMs) may self-extinguish while encountering short-time fire and possess variable phase transition temperatures of 33, 42, 92, and 101°C. Meanwhile, these SB-PCMs own high phase transition enthalpies of 161.4-183.4 J g-1 and excellent cyclic stability. When SB-PCMs as thermal energy management materials in wood plastic-based building materials, they show high adaptability to ambient temperature and excellent thermal management capability, achieving temperature regulation of 9.0°C. Meanwhile, fire safety of the composite wood plastic materials is significantly improved. Detailed anal. confirms that the incorporated benzaldehyde with various positional substituted hydroxyl may induce noncovalent interactions (mainly hydrogen bond and π-π stacking) of SB-PCMs and further control their self-assembling processes, thus achieving multiple thermal responses of SB-PCMs; self-crosslinking charring of benzaldehyde-based Schiff base structure may retard fire spreading, therefore presenting mol. firefighting. Addnl. multistage thermochromic behaviors of SB-PCMs may extend their application in temperature-sensitive paint, intelligent fabric, etc. This work firstly represents a method for manipulating the multistage thermal and fire responses of PCM in the case of fulfilling high thermal energy management capacity and confirms its mol.-firefighting and energy efficient application in building materials.

A new approach for the preparation of durable and reversible color changing polyester fabrics using thermochromic leuco dye-loaded silica nanocapsules was written by Zhang, Wan;Ji, Xiaoqian;Zeng, Chanjuan;Chen, Kunlin;Yin, Yunjie;Wang, Chaoxia. And the article was included in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices in 2017.Recommanded Product: Crystal violet lactone This article mentions the following:

Durable, reversible color changing polyester fabrics were successfully fabricated via a new approach of dyeing with thermochromic leuco dye-loaded silica nanocapsules (TLD@SiO2). TLD@SiO2 was prepared via tetra-Et orthosilicate hydrolyzation and condensation on the surfaces of emulsified thermochromic leuco dye (TLD) nano-droplets by a sol-gel method. The TLD@SiO2 was about 20 nm in size, and its shell could provide protection for TLD. The color of TLD@SiO2 changed from dark blue (25 °C) to light blue (45 °C) and white (80 °C), reversibly. The thermochromic mechanism originated from the conjugation structure conversion of the crystal violet lactone which was confirmed by d. functional theory calculations The shell materials (Si-O-Si) of TLD@SiO2 could be hydrated in water with temperature increase and produced hydrophilic hydroxyl groups for further treating polyester fabrics. These resulting polyester fabrics exhibited excellent thermochromic performance with a color transition temperature of 45 °C. Their color reversibly changed from dark blue (K/S = 12) to light blue (K/S = 2) at 610 nm for more than 50 times. Meanwhile, thermochromic polyester fabrics dyed at 130 °C displayed good color fastness.

Intramolecular Charge Transfer with Crystal Violet Lactone in Acetonitrile As a Function of Temperature: Reaction Is Not Solvent-Controlled was written by Druzhinin, Sergey I.;Demeter, Attila;Zachariasse, Klaas A.. And the article was included in Journal of Physical Chemistry A in 2013.HPLC of Formula: 1552-42-7 This article mentions the following:

Intramol. charge transfer (ICT) with crystal violet lactone (CVL) in the excited singlet state takes place in solvents more polar than n-hexane, such as Et acetate, THF, and acetonitrile (MeCN). In these solvents, the fluorescence spectrum of CVL consists of two emission bands, from a locally excited (LE) and an ICT state. The dominant deactivation channel of the lowest excited singlet state is internal conversion, as the quantum yields of fluorescence (0.007) and intersystem crossing (0.015) in MeCN at 25 °C are very small. CVL is a weakly coupled electron donor/acceptor (D/A) mol., similar to an exciplex 1(AD+). A solvatochromic treatment of the LE and ICT emission maxima results in the dipole moments μe(LE) = 17 D and μe(ICT) = 33 D, much larger than those previously reported. This discrepancy is attributed to different Onsager radii and spectral fluorometer calibration. The LE and ICT fluorescence decays of CVL in MeCN are double exponential. As determined by global anal., the LE and ICT decays at 25 °C have the times τ2 = 9.2 ps and τ1 = 1180 ps, with an amplitude ratio of 35.3 for LE. From these parameters, the rate constants ka = 106 × 109 s-1 and kd = 3.0 × 109 s-1 of the forward and backward reaction in the LE ⇄ ICT equilibrium are calculated, resulting in a free enthalpy difference ΔG of -8.9 kJ/mol. The amplitude ratio of the ICT fluorescence decay is -1.0, which signifies that the ICT state is not prepared by light absorption in the S0 ground state, but originates exclusively from the directly excited LE precursor. From the temperature dependence of the fluorescence decays of CVL in MeCN (-45 to 75 °C), activation energies Ea = 3.9 kJ/mol (LE → ICT) and Ed = 23.6 kJ/mol (ICT → LE) are obtained, giving an enthalpy difference ΔH (= Ea – Ed) of -19.7 kJ/mol, and an entropy difference ΔS = -35.5 J mol-1 K-1. The ICT reaction of CVL in MeCN is not barrierless. The ICT reaction time of 9.2 ps is much longer than the mean solvent relaxation time of MeCN (0.26 ps), indicating, in contrast with earlier reports in the literature, that the reaction is not solvent controlled. This conclusion is supported by the observation of double exponential LE and ICT fluorescence with the same decay times. In the experiment, the researchers used many compounds, for example, Crystal violet lactone (cas: 1552-42-7HPLC of Formula: 1552-42-7).
